Strange ... I was aiming to get either an Asus S56 or S46 but noticed some off figures in the first page. The S56 & S46 is generally the same model as K56 & K46. On the first page, you've posted that the K46 is using an Nvidia GT645M GPU. I've personally not heard of the Nvidia GT645M. Shouldn't it be GT635M? Anyway, IF it really is the GT645M, drop me a pm. I'd be very interested based on your below 2k price. Was planning to get it around this week or next week.

And for the Asus N56VZ, the GPU should be GT650M.
